It's impossible to live in America and never go through a drive thru. Because of that there have been some unique situations that have happened at the drive thru window. Here's just a few...
“One night, guy pulls up to the window…”

“I work at Tim Hortons. One night, guy pulls up to the window. As I take his money, I think I saw his di_k in his hand but I wasn’t completely sure since it was dark. I already took his $20 bill and I owe him his change so this time when I open the window I look down at his lap, sure enough he is pleasuring himself. Except his junk wasn’t even erect, he was just jerking this small floppy p_nis. I froze for a few seconds, then gave him his change and said have a good night and shut the window.”
“I remember thinking he always seemed real lonely…”

“There was this one man who came through the drive thru, late 30s, clearly a farmer from his vehicle and dog in the back. I remember thinking he always seemed real lonely or was sad when he drove through, and tried to carry conversation with me. I felt bad having to be quick with him and dart off, because he just seemed like he wanted someone to talk to. Long story short, he drove through one day and asked if my last name was what he thought it was. After a sideways glance from my manager, I said it was. He looked real sad and took his hat off, said that he reckoned he was my dad. My bio-mother didn’t know who my dad was (she slept around as a teen, then got pregnant with me), so it was possible. My manager let me go on break. So over my dinner he explains that he slept with my mother around the time that she got pregnant, he was only 16. He was really apologetic/kind of seemed ashamed, and said he said he was real sorry he didn’t seek me out, make sure I wasn’t his, that sort of thing. He was from a town about an hours drive away, so that was a part of it. And none ever showed up to tell him he was a dad or anything. I told him I was happy with my life, gave him my number and told him to give me a bell sometime. And yeah, that’s how I met my dad. My bio-dad, I should say.”
“One time I was really distracted and I took…”

“I used to work at Tim Hortons and when I had to work on the window I would barely ever look out it if it was crazy busy. I’m 6′-2”, for me to look out of the window I basically have to double over and look through it was so low. Anyways, one time I was really distracted and I took the persons money and didn’t look and handed the coffee out the window and let go when I felt a hand grab the cup. Immediately I heard ‘oh sh*t!’ so I look out the window and the guy has nubs for fingers and is waving his hand back and forth trying to get control of the cup enough to bring it in his car. I apologize profusely and he leaves after a couple minutes.”
“When we opened the window to explain…”

“I once worked at a Dunkin Donuts for a few months, until I realized I hated that shtty job. Once we had a lovely woman pull up at the drive through twenty minutes before open. Naturally my co-worker and I ignored her while we hurried to setup because without the headset on, we had no idea she was even there. And there was no way I was putting that thing on a minute earlier that I had to. Eventually she pulled up to the window with a pissed, evil-looking face. We gestured, ‘sorry’ and that we weren’t open yet. Apparently she took it personally and started banging on the glass. When we opened the window to explain that we couldn’t serve her yet, she began cursing and squeezed her fat a** out of the car, and hung thru the window spewing off insults. We just stared in awe. I think we told her the cops were coming or something and she left. She was a crazy btch.”
“The strangest incident would have to be the kid who…”

“I worked at McDonalds for almost two years. The strangest incident would have to be the kid who attempted to pay me in pokemon cards by explaining how much each was worth on eBay. When I explained to him that his cards could not be used as currency he became upset, accused me of being a ‘dirty Yu-Gi-oh fan’ and drove off, leaving me confused with both his cards and his food.”
“We felt bad for him, and we gave him a…”

“Not while working the window, but one Fourth of July my then-girlfriend and I were at the drive-thru at McDonalds, and the guy working the window expressed his disappointment that he wasn’t able to see the city fireworks. We felt bad for him, and we gave him a few boxes of sparklers we had so he could light them up after work.”
“I was out in the car-park taking care of bins when a…”

“I was out in the car-park taking care of bins when a big bulky family car that had just been through the drive thru started circling and revving profusely. It caught my attention because it wasn’t like it was a sports car and I didn’t get why he was revving. I soon found out it was because his kid had gotten the wrong topping on his Ice cream, which he yelled through the window at me as he slammed into park right by me. His little b*stard kid threw the ice cream at me, ruining my uniform. I was pretty pissed off so I picked it back up and threw it back at the car. As it was sailing it’s creamy way toward the car again it suddenly dawned on me that this guy might get out and get me fired, so I froze. Luckily it landed on the roof cream side down AND the guy hadn’t noticed! So he drove off with his car wearing a little waffle hat.”
“She said that she wasn’t going to order anything and…”

“I was once working drive – thru orders and this lady came up the speaker, I greeted her and then told her to order whenever she was ready. She said that she wasn’t going to order anything and that she just needed someone to talk to. The customer is always right so I talked with her about how my day was going and then she told me she has herpes. I was dumbstruck, this lady probably just found out she had herpes and the only one she could talk to was the drive – thru guy? I was floored and talked to her for a few minutes and then she said that she had better go unlike the herpes she had. Never saw her face or even her car. I kinda wish I had her come to my window.”
“Once, someone drove a truck to the window with a….”

“Once, someone drove a truck to the window with a bed in the back. Another person got out, put the bed next to the window, and ordered their food, sitting on the bed to wait. The driver left. After receiving her food the bed woman carried the bed to a parking space, got in, and ate.”
“Then before we could hand his food out to him we noticed…”

“Had a man and woman come thru and order. They get to the window and he falls asleep in the 60 seconds he is sitting there. The lady wakes him up and he pays. Then before we could hand his food out to him we noticed his truck started to roll. I get to the window in time to see the truck scraping the building. He got onto the highway woke up and floored it. He came back 30 minutes later and ordered something completely different. He didn’t know that he had been by KFC already. Manager called cops and we kept him in the drive thru until they got there.”
“Because I want extra pickles on that…”

“A couple years ago, I worked at a drive thru and this guy came around to pay. When he got there, he asked ‘hey, did I say I wanted extra pickles on that? Because I want extra pickles on that.’ I informed him that his burger was already made and ready to go, but offered to have a new one fixed up with a satisfactory amount of pickles. the man paused, then had a look of realization. He looked up and said ‘Don’t worry about it! Now that I think about it, I think I might have some extra ones right here.’ this valued customer then proceeded to open up his glove compartment and pull out a giant jar of sliced pickles. It was weird.”
“I open the window, and he looks me dead in the eye, and…”

“When I was in high school I worked at a burger joint. At first they’d always put me on the fryer, and that fking su*ked. The guy who supervised me was Joe. Joe was pretty much a dk, and was always yelling at me for some sh_t. Way above and beyond new guy sh_t…. Anyways, one day they take me off that son of a b_tch fryer, and put me on the window. Start my shift, and sh_t is going good. Then, near the end of the night this one ole boy rolls back around the drive through. I open the window, and he looks me dead in the eye, and says ‘my tots aren’t f_king done you stupid piece of sh_t’. AND THROWS THE BAG AT ME. Guess who’s on the fryer? THAT PIECE OF SH_T JOE. So, we cooked the guy some more tots and Joe somehow blamed that sh_t on me. I worked there like 5 months. Did not have much fun. Good shakes though.”
“The drink landed quite heavily in the fry oil and…”

“Working at McDonalds my sophomore year of high school, some lady went through the drive through at about 1 AM. Someone accidentally gave her a large diet coke instead of a large coke or something, so she threw the drink back through the window. The drink landed quite heavily in the fry oil and splashed all over one of our co-workers. The girl drove away pretty fast, but the manager got her license plate number off the cameras. She was sued pretty badly.”
“At this point, the woman had said she would not leave the drive thru…”

“Not me, but this happened on my shift. We have a drive thru pharmacy where I work. I typically avoid the drive thru at all costs. A woman came through with a prescription for oxycodone 30mg. This was a little over a year ago, and the DEA was REALLY cracking down hard on pill mills and pharmacies that were providing people with oxy so easily. The pharmacist went to the window, she looked over the woman’s profile, and based on her information, she decided she would not fill the prescription. Upon hearing this, the woman went ballistic. Banging on the window, nasty slurs, threatening to call the corporate office, etc. Once the threats started (‘I’ll come in there and kick your ass’), the pharmacist called me, the manager on duty. At this point, the woman had said she would not leave the drive thru. Cars were piling up behind her honking. She was yelling and screaming at them. I went to the window to tell her to leave or I was calling the cops. She eventually left, and I was left to deal with the aftermath of angry customers who had to wait. To my amazement… The worst part of this entire story… Is while this woman was going insane in my drive thru, her young daughter (a toddler) was sitting in the backseat taking it all in.”
“‘Fourth of July, duh!'”

“I worked at a Taco Bell back in high school and this obviously very rich guy came by weekly in his convertible, Hawaiian shirt, and a blow up doll in the passenger seat. One time he had the usual passenger seat one and two in the back, and I asked him what the occasion was. He said, ‘Fourth of July, duh!'”
“Then I heard a weird noise that sounded like an…”

“I was working at a Tim Hortons in Newfoundland when I was 15. A guy comes up to the speaker box, orders his coffee, and then I heard a weird noise that sounded like an elephant. He approaches the window, lo and behold there is a baby elephant in the back of his pickup. At the drive through. On an island in Canada. I was so confused, but just couldn’t bring up the elephant in the room- or pickup bed I guess.”
“And proceeds to hand me a small…”

“Was working at McDonald’s presenting a few weeks ago and this lady comes to pick up her milkshake and she says to me ‘you’re doing a great job keep it up!’ And proceeds to hand me a small fluffy toy snake. I closed the window and started laughing so hard.”
“Tentatively, I poked my head out of the window and…”

“Was working drive thru at Hardees as my first job. Its about 10pm on a Friday night and someone comes into the drive thru. They order a strawberry malt. As part of my ‘scripting’ I ask if they want to add 2 apple turnovers for $.99. They gleefully agree! Cool! ‘Your total is $3.14, pull to the next window.’ And they didn’t. They were laughing. And there was lots of noise. And the noise continued and there was more laughing. Tentatively, I poked my head out of the window and saw 6 high school kids carrying a sofa. They hauled the sofa to the window and asked for me to dump the milkshake all over the sofa. Whatever, they paid for it so I enjoyed it! When I gave them the pies they proceeded to smash them and smear them all over the sofa. Then they carried it to the parking lot and loaded it onto a truck and drove away.”
“When they pulled up to my window…”

“I worked at McDonald’s for two years, and the strangest thing that happened was when a bunch of teenage boys came through the drive thru in a minivan and ordered an ice cream cone. When they pulled up to my window (it was night so we were down to one window taking money and handing out food) a guy that was laying on the top of the minivan grabbed the cone by the ice cream and they drove off. They proceeded to come back through the drive thru and ask if one of them had left a wallet inside.”
“This woman rolls up in a beat-up Lincoln from the 80s…”

“This woman rolls up in a beat-up Lincoln from the 80s (idk the actual make, forgive me) and has to force the gear stick into park. To paint you a picture, this woman was so incredibly obese that her stomach rested atop the steering wheel, squeezed underneath the steering wheel, and poked through the spaces in the steering wheel. And, for my fellow drive-thru PhT’s, you know how this demographic tends to be: rude and always rushing. So, I see she’s trying to find her prescription and as I’m saying ‘Hi, welcome to–‘ she goes ‘(daughters name)! Where in God’s name is my damn prescription?!’ And I hear a little girl’s voice that timidly saying ‘Mommy, I think you–‘ and then the woman says ‘Aha!’ and pulls the prescription out of her bra. So, gingerly I open the transfer drawer to get the Rx from her and of course she parked too far from the receiving window so she’s struggling to reach and what do you FKING know, the wind catches her Rx and blows it across the parking lot. This horrible troll of a woman starts cursing God and yelling at her daughter, ‘What are you waiting for?! Go get it!!!’ And I kid you fking not, I hear the passenger door open (still couldn’t see this kid past the mom’s profile) and this girl stands out of the car and hobbles over and opens the back door. At first I was like ‘wtf why is she hobbling like a pirate’ and LO AND BEHOLD this little girl reaches underneath the seat and pulls out a prosthetic leg and puts it on and proceeds to clomp down the parking lot to chase the prescription. And that’s one of the weirdest things I’ve seen working the drive-thru window.”
“He then propositioned us with as much free food as we wanted and…”

“One early Saturday morning in high school, my buddy and I were blazing really hard. We had started smoking right after school got out around 2:30p on Friday, and were rolling all the way until around 2a Saturday morning. We were gonzo as sh_t — and we were doing this marathon thing trying to block the munchies. Every time one of got an urge to eat, we would force ourselves to take another rip to tide it off. Long story short: we were toasted. We ended up caving around 2a and driving (I know, dumb to drive) to the nearest Burger King. We go through the drive-thru, it’s totally dead, not a soul or car in the area, and we order a sh_t-ton of food. We pull up to the cashier window, and the cashier is this older 50ish year old dude who seemed to the only one in the entire restaurant. He looks right at us, and asks with total sincerity, ‘you kids got herb?’ My friend and I both bust out laughing, vehemently denying it, naturally. But the man persisted and asked three more times — eventually we caved and said yeah, we did. He then propositioned us with as much free food as we wanted and could eat that morning if we split a blunt with him in the back. We naturally fking agreed. We met him around back near the dumpsters, rolled a paper, and blazed the sh_t out of the back of the BK. We finish the blunt, he proposes we roll another. We decline. He gets mad. Starts charging at my buddy, trying to take the rest of the weed stash. I help him fight this rouge BK worker off, and the guy is absolutely irate. Yelling and sh_t, freaking the fk out. We sprint back to the car, and peel the f**k out. We looked back and the dude was chasing us down the road on foot. Wild.”
